Use the Redpanda hosting integration to model a Kafka-compatible broker in an Aspire AppHost. For an introduction, see Get started with Redpanda integration.

import { createBuilder } from './.aspire/modules/aspire.mjs';

const builder = await createBuilder();
const redpanda = await builder.addRedPanda('redpanda');

const api = await builder.addProject('api', '../Api/Api.csproj');
await api.withReference(redpanda);
await api.waitFor(redpanda);

await builder.build().run();

var builder = DistributedApplication.CreateBuilder(args);
var redpanda = builder.AddRedPanda("redpanda");

builder.AddProject<Projects.Api>("api")
    .WithReference(redpanda)
    .WaitFor(redpanda);

// After adding all resources, run the app...
builder.Build().Run();

The resource exposes the kafka endpoint for host connections and an internal endpoint for container-to-container traffic. It also exposes the Schema Registry and Admin API. Aspire assigns a host port for the Kafka endpoint unless you pin one with the port argument.

Configure resources

Redpanda defaults to one CPU and 1G of memory. Use the C# options callback to change these values:

var redpanda = builder.AddRedPanda("redpanda", options =>
{
    options.CpuCount = 2;
    options.Memory = "2G";
});

Set the broker’s host port in TypeScript with addRedPanda('redpanda', { port: 9092 }). The TypeScript API does not expose the resource sizing callback.

Use a data volume or bind mount to persist broker state across container restarts:

TypeScript
C#

const redpanda = await builder.addRedPanda('redpanda');
await redpanda.withDataVolume();
// Or use a host directory:
// await redpanda.withDataBindMount('./redpanda-data');

var redpanda = builder.AddRedPanda("redpanda")
    .WithDataVolume();
// Or use a host directory:
// var redpanda = builder.AddRedPanda("redpanda")
//     .WithDataBindMount("./redpanda-data");

Add a web console

Use either Redpanda Console or Kafka UI. The integration connects each UI to the broker and its Schema Registry.

TypeScript
C#

const redpanda = await builder.addRedPanda('redpanda');
await redpanda.withConsole({
  configureContainer: async (console) => {
    await console.withHostPort({ port: 8080 });
  },
});

// Or use Kafka UI:
const redpandaWithKafkaUi = await builder.addRedPanda('redpanda-ui');
await redpandaWithKafkaUi.withKafkaUI();

var redpanda = builder.AddRedPanda("redpanda")
    .WithConsole(console => console.WithHostPort(8080));

// Or use Kafka UI:
var redpandaWithKafkaUi = builder.AddRedPanda("redpanda-ui")
    .WithKafkaUI(kafkaUi => kafkaUi.WithHostPort(9000));

The TypeScript withHostPort export targets Redpanda Console. C# also supports a Kafka UI-specific WithHostPort overload; the TypeScript API can start Kafka UI but cannot pin its host port.

AppHost API

Method	Purpose
`AddRedPanda` / `addRedPanda`	Add a broker, optionally specifying its Kafka host port.
`WithDataVolume` / `withDataVolume`	Persist broker state in a volume.
`WithDataBindMount` / `withDataBindMount`	Persist broker state in a host directory.
`WithConsole` / `withConsole`	Add Redpanda Console.
`WithKafkaUI` / `withKafkaUI`	Add the Kafka UI container.
`WithHostPort` / `withHostPort`	Set Redpanda Console’s host port. C# also supports setting the Kafka UI host port.
